ab4046970b * Add fixed-size template versions of corner(), start(), end().
* Use them to write an unrolled path in echelon.cpp, as an
  experiment before I do this LU module.
* For floating-point types, make ei_random() use an amplitude
  of 1.

dcebc46cdc - cleaner use of OpenMP (no code duplication anymore)
using a macro and _Pragma.
- use OpenMP also in cacheOptimalProduct and in the
  vectorized paths as well
- kill the vector assignment unroller. implement in
  operator= the logic for assigning a row-vector in
  a col-vector.
- CMakeLists support for building tests/examples
  with -fopenmp and/or -msse2
- updates in bench/, especially replace identity()
  by ones() which prevents underflows from perturbing
  bench results.

371d302efb - merge ei_xpr_copy and ei_eval_if_needed_before_nesting
- make use of CoeffReadCost to determine when to unroll the loops,
  for now only in Product.h and in OperatorEquals.h
performance remains the same: generally still not as good as before the
big changes.

afc64f3332 a lot of renaming
internal classes: AaBb -> ei_aa_bb
IntAtRunTimeIfDynamic -> ei_int_if_dynamic
unify UNROLLING_LIMIT (there was no reason to have operator= use
a higher limit)
etc...

2ee68a074e generalized ei_traits<>.
Finally the importing macro is named EIGEN_BASIC_PUBLIC_INTERFACE
because it does not only import the ei_traits, it also makes the base class
a friend, etc.

9d9d81ad71 * basic support for multicore CPU via a .evalOMP() which
internaly uses OpenMP if enabled at compile time.
 * added a bench/ folder with a couple benchmarks and benchmark tools.
